In this post, we are investigating our daily use of the main protocols used when accessing the Internet while using our smartphone, laptop or desktop computer, tablet, smartTV or game console. Protocols are an essential concept to enable network communications…
Hair & Beauty Salon – Entity Relationship Diagram (ERD)
“Stylish” is a Hair & Beauty Salon offering a wide range of hair & beauty treatments to customers. They currently employ five hair stylists and three beauticians. They currently use a notebook to record all their information such as customer…
Creating Logic Gates using Transistors
As you know, computers can only process binary data which consists of 0’s and 1’s. This is due to the fact that the main processing components (e.g. the CPU) are made of transistors: tiny electronic switches that can be turned…
The Lost Roman Sundial
Roman Britain was a period of nearly 400 years between AD 43 to AD 410 when large parts of Great Britain were under occupation by the Roman Empire. During this period, the Romans built roads and architectural structures that can…
